Anonymous users2024-02-05Vacuum generator and suction cup must not be matched at will, simply put, the vacuum generator only has three parameters, a consumption of compressed air flow, a vacuum flow, and a vacuum. Of course, if you need the same suction cup with different generators, then it must be the kind of generator with high vacuum degree that can make the suction power of the suction cup greater. Therefore, the generator generally has two designs, vacuum type and flow type.
If you require a larger suction cup per unit area, then you choose the vacuum type, if you require a larger vacuum pumping capacity, for example, if you use a suction cup to suck breathable things, such as wooden boards, then your generator has to choose the flow type, because if you choose the vacuum type, there is no guarantee of vacuum pumping flow, then the vacuum degree still cannot go up, that is, the highest vacuum working performance of the generator cannot be reached. With the standard, it is equivalent to how to design, first determine whether it is a flow type or a vacuum type, and then design according to the flow rate, this design is equivalent to the concept of water in the pump pool, (whether it is a vacuum type or a flow type, as long as the pumping flow is large) is equivalent to a large water pump, pumping is fast. The next step is to calculate the presence of Chinese water in the pool.
Water is the air that the generator needs to pump out, and what about China?There is air to be pumped out in the suction cup, there is in the vacuum pipeline, there are also vacuum components (filters, solenoid valves, vacuum tanks, etc.), you calculate the volume that needs to be pumped, and then multiply it by a certain multiple is the basis for selection, in addition, even if you do not consider the leakage of the vacuum pipeline, there must still be leakage between the suction cup and the surface of the workpiece suction, for example, the workpiece is uneven, or the workpiece itself has air permeability, and the multiple of the pumping flow rate will be increased. For the ideal situation that the surface is not breathable and the vacuum line is leak-free, you can use as many small vacuum generators as you want to drain the air, but the difference in the length of time it takes, and this length of time is the design requirements you put forward in the redesign, or the working performance of the system.

Anonymous users2024-02-03Didn't the previous one be controlled with a solenoid valve?Is it a manual valve test?If it is a manual valve, you must replace it with a solenoid valve, if it was a solenoid valve before, then why buy a new solenoid valve?
However, regardless of the manual valve or the solenoid valve, it should be OK to use two tees, and the tees are connected, 1. Vacuum generator (vacuum pump or vacuum generator); 2. a suction cup; 3. Atmosphere. Like your previous design, if you don't use compressed air to blow back, when the suction cup breaks the vacuum, the atmosphere automatically enters the suction cup, but there will definitely be residual vacuum in the suction cup, especially as you said, this kind of suction cup from below firmly supports the workpiece, because the workpiece has its own weight, and the self-weight of the workpiece after breaking the vacuum will press the suction cup to retain part of the deformation state of the suction cup (there is a vacuum if there is deformation, but it is just the difference between the vacuum degree and the size of the residual vacuum suction). ), the air pressure entering the suction cup is still less than 1 bar (the standard atmospheric pressure outside the suction cup).
Compressed air backflushing can indeed eliminate the residual vacuum of the suction cup, only need to connect the compressed air to the atmospheric interface of the solenoid valve, so that when the vacuum is broken, the pressure that enters the suction cup is several times that of the air, and the air pressure in the vacuum suction cup is higher than 1bar, and there will be no residual vacuum suction when the workpiece is separated from the suction cup.

Anonymous users2024-02-01If there is no other pneumatic auxiliary action for a separate suction device, only the following:
1. Suction cups. 2. Vacuum transmitter.
3. Solenoid valve.
Can. Of course, if you want to test the vacuum, you need to add a vacuum pressure switch, and in addition, you need to add a vacuum filter to protect the vacuum emitter. Tracheal joints are also indispensable.
If there is other action (other than blotting), an air pump is required.
The air pump is not a vacuum pump, the air pump provides a positive pressure compressed air source as a pneumatic power source.
A vacuum pump is the opposite of an air pump and provides a negative pressure power source.
Of course, you can also simply understand that the air pump is for the outlet, and the vacuum pump is for the inhalation. In addition, with a vacuum emitter, there is no need for a vacuum pump.

Anonymous users2024-01-27There are many negative pressure solenoid valves, just choose one.
To balance off the negative pressure, it is generally at the vacuum suction cup, connected to a controllable air path. When the object is put down, send some air.

Anonymous users2024-01-26In the process of industrial production, it is often necessary to change the liquid of the equipment and clean up the wastewater, and the usual practice is to use an electric pump to drain it, but it is often not completely discharged, and it needs to be rinsed repeatedly, and finally the residual night is sucked dry by manual use of a rag or mop. In this way, the fluid cannot be quickly drained and is labor-intensive and time-consuming.
The purpose of the invention is to provide a kind of operation that utilizes the siphon principle to carry out cleaning operations, to produce a device for vacuum adsorption through negative pressure, to realize the rapid labor-saving and time-saving completion of the work of suction waste liquid.

Anonymous users2024-01-24In this case, the method of electric contact negative pressure vacuum gauge + solenoid valve + vacuum pump + air pump can be used, and the specific method is:
1. Install an electric contact negative pressure vacuum gauge on the gas pipeline of the suction cup, and when a certain negative pressure is reached, the pressure gauge sends an electrical signal to the solenoid valve, and the solenoid valve closes the gas pipeline; When it is lower than a certain negative pressure value, the solenoid valve is connected to the gas pipeline. This step solves the problem of air intake and maintenance of negative pressure in the suction cups.
2. In order to make the object fall off quickly, it is necessary to quickly inject appropriate air into the suction cup while stopping the supply of negative pressure in the suction cup, which also depends on the solenoid valve (pneumatic valve). This solenoid valve (pneumatic valve) should be a three-position solenoid valve, that is, the solenoid valve should have three functions: opening and closing conversion.
Consider using a pneumatic five-way three-position solenoid valve (pneumatic valve) instead.
3. The above is just a general idea, and some specific air pressure values and negative pressure values still need to be tested to achieve. In addition, the action speed of the solenoid valve is not as fast as the pneumatic valve, which means that the action of the valve is realized by air, not by the electromagnet.

Anonymous users2024-01-22This depends on your specific requirements, for example, a very small vacuum generator can control more than n large suction cups, but the time will be pumped for a long, long time, but if you take a large vacuum generator, to control a small nature, so that you can instantly suck, control the time, and your required reaction time
